Answer 1

Respuesta:

Explicación paso a paso:

$\frac{3}{9} + \frac{6}{12} =?$

9 x 6 = 54

$\frac{3}{9} + \frac{6}{12} = \frac{54}{y}$

3 x 12 = 36

$\frac{3}{9} + \frac{6}{12} = \frac{54+36}{y}$

9 x 12 = 108

$\frac{3}{9} + \frac{6}{12} = \frac{54+36}{108}$

54 + 36 = 90

$\frac{3}{9} + \frac{6}{12} = \frac{54+36}{108} = \frac{90}{108}$

$\\\large{\blue\boxed{ahora\:lo \:volvemos\: en\: pequeno\: la\: fraccion}}$

$\frac{90}{108} = \frac{45}{54}$

$\frac{3}{9} + \frac{6}{12} = \frac{54+36}{108} = \frac{90}{108}=\frac{45}{54}$
